GENERAL DESCRIPTION
The EV2364/1541-00A is an evaluation board
for DSL Power applications. It has four outputs
and can supply 1.5A continuous output current
over a wide input supply range with excellent
load and line regulation. Current mode
operation provides fast transient response and
eases loop stabilization. Fault condition
protection includes cycle-by-cycle current
limiting and thermal shutdown.
